Windows: Orzeszek Timer is a dead simple timer with flexible inputs. You can enter in countdown commands in over a half dozen different ways for quick and easy timer creation.

Orzeszek Timer is a very basic timer tool that excels at accepting different input formats. Here is just a sample of time formats that Orzeszek accepts:

5 – 5 minutes

2.5 – 2 minutes 30 seconds

1d 5h 3m 25s – 1 day 5 hours 3 minutes 25 seconds

1.05:03:25 – 1 day 5 hours 3 minutes 25 seconds

1 5 3 25 – 1 day 5 hours 3 minutes 25 seconds

01/01/2011 – until midnight on 1 January 2011

01/01/2011 5:00 PM – until 5:00 pm on 1 January 2011

Orzeszek Timer is even command line compatible so you can make shortcuts for routine countdowns you use (the Pomodoro Technique, timing your tea, and so on). Orzeszek Timer is freeware, Windows only. Thanks Elijah Snail!
